> ParseSpecification.java:1625 produces NPE

> Key: TAPESTRY-2102
> URL: https://issues.apache.org/jira/browse/TAPESTRY-2102
> Project: Tapestry
> Issue Type: Bug
> Affects Versions: 4.1.3
> Environment: XP Pro, maven-2.0.8, eclipse-3.3.1.1, ognl-272-snapshot
> Reporter: Kenneth William
>
> All I am doing is extending Image component to animate some live transparent text on it.
> The following code does not check for null on resource.
> Therefore... for whatever reason my webapp is not parsing... it produces NPE.
> There should be a check here.
> I am researching the reason why getResource() returns null.
> ParseSpecification.java:1625
> private void parseDocument()
> {
> InputStream stream = null;
> Resource resource = getResource();
> boolean success = false;
> try
> {
> if (_parser == null)
> _parser = _parserFactory.newSAXParser();
> URL resourceURL = resource.getResourceURL();
